The speed sensor in a 1994 Honda Accord EX is a critical component that helps the vehicle's computer monitor the speed of the car, which is vital for accurate speedometer readings and proper functioning of the cruise control system.

Speed Sensor Location

The vehicle speed sensor (VSS) on the 1994 Honda Accord EX is located on the transmission. Specifically, it can be found:

  • Underneath the air intake system: To access it, you will need to remove the air filter housing and intake duct. This will provide better visibility and access to the sensor.

  • Positioned near the firewall: When looking at the engine from the passenger side, the VSS is situated close to where the transmission connects to the engine, just above where the axles enter the transmission.

  • Below the throttle body: The sensor is typically about 6-8 inches below and slightly to the left of the thermostat.

Accessing the Speed Sensor

To effectively reach and replace the speed sensor, follow these steps:

1. Remove the air filter housing: This involves unscrewing several bolts (usually 8mm) that secure it in place.

2. Disconnect any attached wiring harnesses: Be cautious while disconnecting these connectors to avoid damaging them.

3. Locate the VSS: Once you have removed the air intake components, you should see the speed sensor mounted on top of the transmission.

4. Unscrew and remove: The VSS is typically secured with a single bolt (10mm). After removing this bolt, gently pull out the sensor.

5. Inspect and replace: Check for any debris around the mounting area before installing a new sensor to prevent contamination of the transmission.

Important Notes

  • Ensure that you have appropriate tools on hand, such as a 10mm socket, Phillips screwdriver, and pliers.

  • It’s advisable to wear gloves and safety glasses while working on your vehicle to protect yourself from any debris or sharp components.

  • If you're experiencing issues with your speedometer or cruise control, replacing a faulty speed sensor may resolve these problems.

By following these steps and tips, you can successfully locate and replace the speed sensor in your 1994 Honda Accord EX, ensuring your vehicle operates smoothly and accurately.
